Abstract
A gas scrubber cone condition monitoring system has a sealed gas scrubber cone (9) moveably mounted in a gas pipe (1), a collar (5) fixedly mounted radially outward of the cone in the gas pipe and a pressure tap (12) into the sealed cone. The pressure tap is coupled to a condition monitor (17, 18) via an input line (16). An output line (14) from the condition monitor is coupled to a gas pipe (15), downstream of the sealed cone. The condition monitor includes at least one of a pressure gauge and a gas flow meter.
Claims10
A gas scrubber cone condition monitoring system comprising:
- a gas vessel through which gas flows from upstream to downstream;
- a sealed gas scrubber cone moveably mounted in the gas vessel;
- the cone has a narrower end upstream in the gas vessel and a wider end downstream in the gas vessel;
- the cone comprises the gas scrubber cone and a baseplate over the wider end of the cone for forming a sealed enclosure in the cone;
- a condition monitor comprising at least one of a pressure gauge and a gas flow meter;
- a pressure tap into the sealed cone, an input line coupling the pressure tap to the condition monitor;
- an output line from the condition monitor to a downstream gas area, downstream of the sealed cone;
- and
- a collar fixedly mounted radially outward of and opposing the cone in the gas vessel for defining a passage for the gas between the collar and the cone, and such that movement of the cone in the gas vessel adjusts the flow and the pressure of the gas passing the cone.
A method of scrubber cone condition monitoring, comprising:
- providing a sealed scrubber cone for use with a gas scrubber wherein the sealed scrubber cone comprises a gas scrubber cone and a baseplate over a wider end of the cone for forming a sealed enclosure in the cone;
- inserting a pressure tap into the sealed cone enclosure;
- and
- measuring pressure in the sealed cone at a condition monitor;
- comparing the measured pressure with an expected sealed cone pressure value;
- and providing an indication of a fault condition if the result of the comparison exceeds a predefined value.
